Downtown Tulsa’s 90-year-old Gates Hardware building is getting spruced up for the 21st century. KSQ Architects has acquired the property and will move its 47-person staff there after an extensive renovation.

Located at 216 N. Elgin Ave. in Tulsa’s Greenwood Historic District, the 28,000-square-foot building takes its name from the Gates Hardware store it once housed. On the 14,000-square-foot first floor, one of two tenant spaces will be occupied by a sports concept brewpub from McNellie’s Group and Marshall Brewing Co.

KSQ itself will take the Gates building’s entire second floor, relocating its office from 406 South Boulder Ave. Highlights of the renovation will include an overhaul of the concrete and masonry structure, as well as upgrades to the parking area and the building’s façade. Plentiful glass will afford views of ONEOK Field, the home of the Tulsa Drillers baseball team, which is located across the street.

“Our Oklahoma staff has been a part of downtown Tulsa for many years, and buying the Gates building is furthering our commitment to revitalization and the city as a whole,” KSQ Principal and President David Short said in a statement. “It’s already been an adventure to redesign this historic space, and every architect wants to design their own office from the inside out so this suits us well.”

Ross Group Construction is the general contractor for the project, which is scheduled for completion this fall.
